Can Bracing Correct Spinal Curves from Scoliosis?
If you know someone with scoliosis, you may have heard that wearing a brace does not correct a spinal curve, it merely stops the curve from getting worse.
The new Boston Brace 3D from Boston Orthotics & Prosthetics uses an improved brace design with a unique shift/push combination of forces that move the spine into a corrected position. That means the right scoliosis brace, worn for the prescribed amount of time, may actually improve a spinal curve.
Typical Spinal Curve Correction Using the Boston Brace
Boston O&P measures curve-correction outcomes by taking an X-ray of the spinal curve before bracing begins and comparing it with an in-brace X-ray (i.e., when the patient is wearing the brace).
The goal is to see at least a 50% reduction in the curve between the pre-brace and the in-brace X-rays. For example, if the patient’s initial Cobb Value is 30, an in-brace X-ray ideally would show the Cobb Value at 15. That said, there are many factors that influence the amount of tolerable correction. Some curves see well in excess of 50% while others may see around 30%. The goal is to obtain correction without compromising the patient’s ability to wear the brace.
The final measurement showing the correction of the scoliosis curve is taken with an out-of-brace X-ray (i.e., when the patient is not wearing the brace), usually after the bracing is complete.
Types of Scoliosis Curves
The amount of spinal curve correction depends on a number of factors, including the type of curve and where it is located on the spine.
Thoracolumbar curves, which are located in the lower thoracic (mid-back) and upper lumbar (lower back), typically see the highest level of correction, followed by curves that occur exclusively in the thoracic and lumbar regions. Bracing is also more successful with small, single curves—it’s more difficult for bracing to achieve the 50% curve reduction goal when the curve is larger or more complex.
With treatment using the Boston Brace Original, for curves that start at 25-30 degrees, the average curve reduction is 41-60% depending on the location of the curve. For curves of 31-35 degrees, the average curve reduction is 48-52%, and for curves of 36-40 degrees, the average curve reduction is 50-56%.
In a study of bracing results for idiopathic scoliosis using the Boston Brace, 39% of patients had a spinal correction of 5 degrees or more, at least a year after completing bracing treatment.
The Boston Brace 3D achieves even higher levels of curve correction. For single thoracolumbar curves, the average curve correction is 62% for the Boston Brace 3D compared to 55% for the Boston Brace Original. For single thoracic curves, the average curve correction is 57% for the Boston Brace 3D compared to 52% for the Boston Brace Original.
Scoliosis Curves: Preventing Progression vs. Actual Curve Correction
It’s important to note that treatment with the Boston Brace, or any scoliosis brace, will not eliminate a spinal curve. The goal of bracing is, at the minimum, to prevent the curve from getting worse when the patient is still growing, and hopefully keep the spinal curve small enough that the patient will not need surgery. The combination of in-brace curve reduction and adherence to the prescribed wear schedule has been shown in multiple studies to reduce the risk of curve progression.
In some cases, the curve can actually be improved with bracing, but that depends on a number of factors, including the type and degree of curve, age at diagnosis, the level of compliance with the wear schedule, and how the body of each individual patient responds to bracing as a treatment for scoliosis.
“Just a few years ago, we were happy when we stopped the curve from increasing, but with our new Boston Brace 3D, we’re almost expecting to see curve improvement,” says Boston O&P clinician Hector Paez.
Boston O&P’s Curve Correction Success Stories
Most patients achieve greater than 50% correction of the primary curve when wearing the Boston Brace 3D according to the prescribed wear schedule. Here are some recent success stories we’ve experienced with the Boston Brace 3D:
- Reagan: After five months of wearing the Boston Brace 3D for 18 hours a day, along with 20 minutes of Schroth therapy five days a week, Reagan’s spinal curve went from a 29-degree curve to 22. >>Read more.
- Lily: A year of wearing the Boston Brace 3D corrected Lily’s spinal curve from 34 to 21 degrees. >>Read more.
- Aubrey: Diagnosed with scoliosis at age 13, Aubrey had a curve of 29 degrees. After being fitted with a Boston Brace 3D, her spinal curve was actually overcorrected, from 29 degrees to -11 degrees. >>Read more.
- Emily: After 14 months of bracing with the Boston Brace 3D and Schroth physical therapy, Emily’s spinal curve was reduced dramatically—from 49 degrees to 11 degrees. The results were so remarkable that the case was featured at the 2019 International Society on Scoliosis Orthopedic and Rehabilitation Treatment (SOSORT) Annual Meeting. >>Read more.
